This invention relates to improvements in toilet cases more particularlyadapted for use in connection with a tooth brush, the main object of theinvention being to provide a novel and improved device of this generalcharacter that may be readily carried in the pocket of the user.

A further object of the invention is to provide novel means for holdinga tooth brush in a tubular enclosure when not in use, with advantagesfrom a sanitary standpoint, and to facilitate projection of the brushfor use without separating the same from any part of the holder.

A further object of the invention is to simplify the construction andarrangement of parts of the enclosing` means for a tooth brush adaptedto be carried in the pocket of the user, and to maintain the brush insuch position at all times that it may be quickly projected for use. ormoved telescopically with relation to the main portion of the holder toshield the same, and also provide in connection with the main part ofthe holder a covering cap or tubular member that may also serve toextend the main part of the holder and render the latter usable as ahandle or grip when the brush is projected for application to the teeth.

1With the foregoing and other objects and advantages in view, theinvention consists in the construction and arrangement of the severalparts which will be more fully hereinafter described and claimed. 1 v

ln the drawing:

Fig. 1 is a perspective view of a tooth brush organization embodying thefeatures ofthe invention and showing the brush projected for use.

Fig. 2 is a longitudinal vertical section through the improved toothbrush organization as shown arranged in Fig. 1.

Fig. 3 is a longitudinal vertical section of the improved tooth brushorganization showing the brush enclosed and fully sealed Within the maintubular casing and tubular cover iitted to the latter.

Fig. l is a transverse vertical section on the line lf-4:, Fig. 2. i

The essential elements of the improved tooth brush case or organizationconsist of a main tubular casing 5. having one end closed, as at 6, andthe opposite end 7 open and formed with interior screw threads 8.Cooperating with the main tubular enclosure 5 is a tubular cover 9,fully open at its one end 10 and having the opposite end closed as atA11. At the open end 7 of the main tubular enclosure 5 the material ofthe said enclosure is slightly thickened, as at 1Q, to provide for theformation of the screw threads 8, the said thickened portion and screwthreads extending only a comparatively short distance from the openterminal of the said main tubular enclosure. The improved tooth brushorganization also includes a brush-carrying headv 13 having a socket 111projecting eccentrically therefrom to tightly receive a handle 15 of atooth brush 16, the

handle 15 in this instance being `shorter s than the handles of toothbrushes as ordinarily constructed, and moreover, the socket 14 isflattened and properly shaped to receive the extremity of the handle 15.The

socket 14 is yieldable or resilient andhas a longitudinal slot 14aeXtending the full length thereof, to permit the said socket to expandwhen the handle 15 is inserted therein Aand thereby increase thegripping action of the socket on the handle. The tooth brush and socketremain intact under ordinary usage of the improved'device, but thehandle 15, by sufficiently forceful pulling action, may be withdrawnyfrom the socket rand the tooth brush 16 vreplaced by another brush inthe event the brush becomes worn and 'unt forv further service.The'outer side of the head'13 from which the socket "14.1 projects issmooth and adjacent to the socket is formed with a run of screw threadspermit the insertion of the head 13 in operative relation within themain casing 5, and subsequently the screw-threaded open end`7 of thesaid member may be brought into close engaging relation with respect tothe threads 17 of the head. However, the manner of assembling theseparts is immaterial as a number of methods could be used foraccomplishingthis result. The head 13 is tubular to lighten thestructure, and again referring to the manner of assemblage, the closure6 of the main casing 5 may be formed of a disk set in the head andsecured by. well known mechanical operations.

lWhen the improved tooth brushmorganization is prepared for insertion inthe pocket of the user the threads 17 of the,

from the ouen end 7 of the casino` and preferably applied over theclosed end of the said casing as shown by Figs. 1 and 2, and the brushthen pulled outwardly, drawing the head 13 therewith, and when thethreads 17 reach the threads 8 by suitably revolving the brush, t-hesaid threads 17 are caused to engage the threads 8, and become firmlyand positively seated and hold the brush 16 in the position shown byFigs. 1

andi2, the collar 1'8 then bearing against the inner rear terminal ofthe threads 8 and preventing further egress of the head 1.3, as clearlyshown by Fig. 2. Owing to the format-ion of the groove 19, which is deepenough to be out of contact with the rear Aportions of the threads 8,the collar 18 is rendered effective as a stop means to prevent movementof the head 13V outwardly beyond a predetermined distance. Vhen thecollar 18 bears against. the rear terminal of the threads 8,. the outerside of the said head 13 is flush'with the edge of the open end 7 of themain casing 5. i

The improved'tooth brush holding means as just described is very simplein its operation and may be quickly adjusted to project the tooth brush16 or store or'enclose the latter and shield the same, and. it. isproposed to form the several parts of the improved device with suchdimensions and general proportions that it may be easily carried in thepocket of the user. Through the medium of the enclosing means, or themain casing 5 and cover or cap 11, the tooth brush will be preserved ina sanitary con- 'dition when, not in, use,iand it is also intended thatsuch materials be used in the formation of the mainV casing5, cover orcap 11 and the head 13 withfits several structures as hereinbeforenoted, as. are

suitable forv the purpose and preferably as to prevent corrosion fromdampness of the brush bristles.

lVhat is claimed as new is:

1. A tooth brush organization of the class specified, comprising atubular casing of equal'diameter throughout its length and closedjat oneend and fully open at the opposite end and having internal screw-threadsadjacent the said open end, a cover removably fit-ted over the open endof the casing, a head having outer screw-threads to engage thescrew-threads of the casing and separable from the said casingscrew-threads to permit the head to bev moved inwardly the full lengthof the casing and be located adjacent to t-he `closed end of the saidcasing when the tooth brush organization is notseal'ech the head havinga circumferential groove at the extremity thereof opposite that providedwith the screw-threads and having a circumferential shoulder to abutagainst the inner limit of the screw-- `threads in the open end of thecasing to prevent the head from being moved outwardly beyond the end ofthe casing, and a tooth brush held by and movable with said head forpartial insertion in the casing to permit application of the cover andthereby fully enclose the tooth brush.

2. A tooth brush organization of the class specified, comprising atubular casing open at one end and provided with interior screw threadsin said open end, a head provided with cooperating screw threads on theforward portion thereof to separably engage the screw threads within theend of the `casing and having a circumferential groove and stop shoulderat the end thereof opposite the screw threads thereon to permit thelsaidhead to be detached from the screw threads of the casing and movedlongitudinally the full length thereof into the latter, the headat Vitsouter end having an eccentrically positioned, longitudinally projectingHat socket with a longitudinal slot formed in one side edge portionthereof, and a tooth brush having a handle frictionally fitted in thesaid flat socket, the slotted socket permitting the insertion andwithdrawal ofthe tooth brush handle and the latter and .a part of thebrush together'with the head being movable lengthwise into the casing,acover removably fitted over the screw threaded open end of the casingto fully enclose the brush when not in use, the head and brush beingunitedlymovable inwardly and outwardly and `maintained in connectionthrough the medium of the socket.

In testimony whereof I have hereunto set my hand.
